sascha pointed me yesterday to your patch, i tried it with v2
(http://lkml.org/lkml/2010/3/31/130), but without success.

our distributor informed us that the board they let us is a
preliminary hardware version and that this is probably the cause of
the problem :/

i hope i'll get soon my hands on an offical board release and can
verify that the FEC just works ;)

thanks for your help!
